summary Recent developments in digital technologies and smart materials have created new opportunities and are suggesting significant changes in the way we design and build architecture. Traditionally, however, there has always been a gap between the new technologies and their applications into other areas. Even though, most technological innovations hold the promise to transform the building industry and the architecture within, and although, there have been some limited attempts in this area recently; to date architecture has failed to utilize the vast amount of accumulated technological knowledge and innovations to significantly transform the industry. Consequently, the applications of new technologies to architecture remain remote and inadequate. One of the main reasons of this problem is economical. Architecture is still seen and operated as a sub-service to the Construction industry and it does not seem to be feasible to apply recent innovations in Building Technology area. Another reason lies at the heart of architectural education. Architectural education does not follow technological innovations (Watson 1997), and that “design and technology issues are trivialized by their segregation from one another” (Fernandez 2004). The final reason is practicality and this one is partially related to the previous reasons. The history of architecture is full of visions for revolutionizing building technology, ideas that failed to achieve commercial practicality. Although, there have been some adaptations in this area recently, the improvements in architecture reflect only incremental progress, not the significant discoveries needed to transform the industry. However, architectural innovations and movements have often been generated by the advances of building materials, such as the impact of steel in the last and reinforced concrete in this century. There have been some scattered attempts of the creation of new materials and systems but currently they are mainly used for limited remote applications and mostly for aesthetic purposes. We believe a new architectural material class is needed which will merge digital and material technologies, embedded in architectural spaces and play a significant role in the way we use and experience architecture. As a principle element of architecture, technology has allowed for the wall to become an increasingly dynamic component of the built environment. The traditional connotations and objectives related to the wall are being redefined: static becomes fluid, opaque becomes transparent, barrier becomes filter and boundary becomes borderless. Combining smart materials, intelligent systems, engineering, and art can create a component that does not just support and define but significantly enhances the architectural space. This paper presents an ongoing research project about the development of new class of architectural wall system by incorporating distributed sensors and macroelectronics directly into the building environment. This type of composite, which is a representative example of an even broader class of smart architectural material, has the potential to change the design and function of an architectural structure or living environment. As of today, this kind of composite does not exist. Once completed, this will be the first technology on its own. We believe this study will lay the fundamental groundwork for a new paradigm in surface engineering that may be of considerable significance in architecture, building and construction industry, and materials science.

summary The finding of a functional program for any kind of building involves a great amount of knowledge about the behavior of future building users. This knowledge can be gathered by looking at relevant building literature (Adler, 1999; Neufert and Neufert, 2000) or by investigating the actual processes taking place in similar environments, the latter being demonstrated e.g. by (Schütte-Lihotzky, 2004) or new functionalist approaches of the MVRDV group (Costanzo, 2006)). Both techniques have the disadvantage that the architect might assume a behavior which is seldom experienced in real life (either through lack of information or by failing to meet the building user’s expectations). What is needed is a verification step in which the design is tested on real users. We have devised a game-like environment (Figure 1a) in which it is possible to capture the behavior of future building users in order to verify the relevance of the design even at a very early stage. As result of applying our approach, we can find previously overlooked usage situations, which may be used to further adapt the design to the user’s needs.

title An Evaluation of Neural Spatial Interaction Models Based on a Practical Application

summary One of the serious problems faced by the Brazilian municipalities is the scarcity of resources for building education infrastructure. This asks for an optimal allocation of the available resources that includes, among other things, a rational spatial arrangement of the supply points (i.e., schools) in order to increase the demand coverage (i.e., students). If it is possible to foresee the regions where the demand is going to be concentrated, it is then possible to plan the location of new facilities and to assess the impact on the future level of service of the entire system. Considering that one of the consequences of the location-allocation process is the distribution of trips from demand points to supply points throughout the city, therefore affecting the overall intraurban accessibility conditions to essential services such as education, there is a strong need of models that planners can rely on to predict the future trip distribution patterns. As a result, the objective of this work was to evaluate the performance of Artificial Neural Networks (ANN) when applied to spatial interaction models, the so-called Neural Spatial Interaction Models. This was done in a practical context, in contrast to the more theoretical works commonly found in literature. The practical application showed that the neural spatial interaction model had different performances when compared to the traditional gravity models. In one case the neural models outperformed the gravity models, while on the other case it was just the opposite. The explanation for this may be in the data or in the ANN model formulation, as discussed in the conclusions.

summary Computers in designing are usually considered as a tool for preparing technical documentation, storage and managing information, coordinating of flow of design process, modelling and all kind of visualisations (renderings, animation, VR models). At the early design stages, when an idea of the form is created, computer is not used very often. The reason for this is that traditional computer drawing is too completed to be used at this stage. In new methods of supporting creativity, computer should be used for creation of less precise, unpredictable but more inspiring images. This method are based on the thesis that emotional elements have a great affect on the decision making process in designing. Intuition, unpredictability and no logic are the essence of creativity in the selection of associations. Confirmation of this statement we may find in many theories of creativity (theory of incubation elaborated by Wallas, genploration (Finke, Ward and Smith), redundant generation (Lem), synectics (Gordon)). All these theories emphasize the role of unpredictable associations and metaphors in creativity. Process of metaphorisation is characteristic for our era and plays important role in creative process. That’s why we need the new methods of graphic computer and non-computer transformation, which allows us a fuller exploration of design metaphors. The final conclusion is built on the thesis that too precise tools promote cause to decrease differences.

summary In this paper an object-based CAD programming is used to take advantage of standardization to handle the schematic design, sizing, layout for services in a building ceiling void. From the specification of the building 3D model, our software proceeds through different steps; from the determination of the standard number and size of fan coils to the generation of 3D solutions. In order to deal with more complex geometry and larger problems, we have used a hybrid approach: Case Based Reasoning (CBR) within Constraint Satisfaction Problem (CSP) approaches. In practice, engineers in building services use previous solutions and adapt them to new problems. CBR mirrors this practical approach and does help us to deal with increasingly complex geometry effectively, and meanwhile CSP has been used for layout adaptation. The results have shown that it is possible to define and implement standard solutions to produce designs comparable with current practice. The benchmarking exercise has underlined many advantages and made some suggestions for further development. This project is funded by The Engineering and Physical Sciences Research Council (EPSRC) in UK.

summary Designing is largely a process of (inter)active imaging. The evolvement of a design concept from preliminary design proposal towards spatial and material environment generally follows an uncertain path through uncharted landscape; a journey of exploration which requires both rational and creative consideration, frequently involving the interchange of information within a design team and collaboration with representatives from different contributing disciplines. Designs are conceived, worked out and specified step by step (roughly speaking from ‘rough to fine’) in iterative design ‘loops’. All the time the designer tries to determine which ‘course’ should be taken, by considering reference material, by reflecting on conceptions developed previously and by generating specific options aimed at furthering the ‘concretisation’ of the end product. In the course of such a trajectory, visual information is continually being developed, selected, tested, and subsequently either discarded or perfected. From early times architects have been considered not only as knowledgeable ‘experts’ in the field of building as a craft, but also as ‘creative directors’ of such development processes. The architect should be capable of not only conjuring up visions of the future spatial and material form of the building, but also of conveying these to the other ‘actors’ involved in the initiation and building process. Such ‘sharing’ of information is necessary in order to generate sufficient understanding, consensus, enthusiasm, as well as means. To become more than ‘figments of the imagination’, the designer’s ideas need to be ‘pinned down’ (even if they are not yet entirely finished) and communicated by using some form of reliable – and preferably readable – ‘language’ for design development and communication.

summary The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models.This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. A truss is defined as: “A triangulated arrangement of structural members that reduces nonaxial external forces to a set of axial forces in its members.” (Allen and Iano 2004)Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes.

title GEOMETRY AND ARCHITECTURE: NURBS, DESIGN AND CONSTRUCTION
source Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 135-139.
summary Geometry regarded as a tool for understanding is perhaps the part of Mathematics which is the most intuitive, concrete and linked to reality. From its roots as a tool to describe and measure shapes, geometry as ‘the space science’ , has grown towards a theory of ideas and methods by means of which it is possible to build and study idealised models, not only from the physical world but also from the real world. In graphic architecture thought, geometry usually appears as an instrumental support for project speculation. Geometric procedures are presented as representational resources for the graphic testing of reflection and for the exposition of ideas in order to build a logical order as regards representation and formal prefiguration. The fast rise of computing in the last decades has made it possible for architects to work massively and in a graphic and intuitive way with mathematical representations of tridimensional geometry, such as the NURBS . These organic surfaces of free shapes defined by vectorial curves have allowed access to a rapid generation of complex shapes with a minumum amount of data and of specific knowledge.

The great development of modelling achieved by the digital media and the limitations in the technical and building areas and in the existence of materials which are coherent with the resultant shapes reveal a considerable distance between the systems of ideation and simulation characteristic of the computing era and the analogous systems of production inherited from the slow industrial development. This distance has been shortened by CAD/CAM systems, which are, however, not very accessible to the architectural field. If we incorporate to the development of these divergent media the limitations which are distinctive of the material resources and procedures of the existent local technology, the aforementioned distance seems even greater.

Assuming the metaphor of living at the threshold of two ages (industrial-computing, analogical-digital, material-virtual) and the challenge of the new conceptual and operational tools in our field, we work in the mixture, with no exclusions or substitutions, proposing (by means of the development of informational complements) some alternatives of work to approach the issue under discussion from the Architecture Workshop.

title STUDY ON COMPUTER-AIDED DESIGN SUPPORT OF TRADITIONAL ARCHITECTURAL THEORIES
source Technische Universität München
summary The research presented in this thesis describes a computer-aided design support of traditional architectural theories. Traditional architectural theories in western architecture have been considered as a basis for answering the fundamental questions of architecture: proportion, symmetry, colour, harmony and so on. In particular, the aesthetic aspect of these theories has been one of many important architectural aspects, and which is concerned with the field of architecture in determining the beauty of architectural form. The most significant role of the traditional theories in architecture is to maintain unity, to avoid chaos and then to achieve harmony in a design, using some specific design principles. However, current technology-guided constructions tend to neglect often the importance of these theories due to the standardization of building elements, due to mechanically-prepared construction and the reducing completion costs, etc. Thus, this research proposes a design support system as a design assistant that gives an intelligent advice on architectural design, using analytical design- and ordering- principles of traditional theories for the optimization of the architectural design from the aesthetic perspective. To evaluate the aesthetic quality of an architectural design, this system is implemented in the AutoCAD environment, using the AutoLISP. It is applied so as to explain and develop aesthetic qualities of a design. Designs proposed by this system include optimum designs, which are based on the traditional architectural theories, and new ones which can be in future connected to information models. To do this, the definition of information about building elements is accomplished by using the neutral format EXPRESS and EXPRESS-G for such application systems. The results of the application system are presented, such as the easily generating and quickly conceptualising of an object model, the checking of the aesthetic value of the design during the various design phases, the helping to find direction during rational searching for a solution. The user can easily appreciate the usefulness of the proposed system as a set of tools for searching for rational architectural aesthetics and formal solutions at different design-stages. It is to be hoped that a new "traditional" fundamental of architecture, such as the proposed system, incorporating CAAD systems, will find its place among new technological methods in the AEC industry and so help to bridge the gap between the value of traditional architecture and CAAD systems.

title Testing the relevance of parameterization to architectural epistemology
source Architectural Science Review, Volume 52.2: 135-141
summary Advances in building information modeling (BIM) deeply impact the production of new architecture; its benefits are obvious and its acceptance widespread. But how does BIM impact the study of existing architecture? Can BIM be assumed to operate as a neutral framework, equally applicable to the study of architecture anywhere? Using as a point of departure a recent outline of the conceptual structure of parametric modeling prepared by Sacks, Eastman, and Lee (2004), this paper compares parametric models of two existing works of architecture: Mies van der Rohe’s Crown Hall and Peter Zumthor’s St. Benedict Chapel. The processes of parametrically modeling each building are specifically compared in two ways: first, parameters are established for each model; second, each model is "flexed" as a means of disclosing possible semantic relationships within each work of architecture. Because each building demands a different parameter-establishment strategy, and because the models permit different degrees of flexibility, the comparison illustrates the shortcomings of a "neutral framework" assumption to an architectural epistemology.

title Building a Synthetic Cognizer
source Design Computation Cognition conference 2004, MIT
summary Understanding ‘space’ as a structured and dynamic system can provide us with insight into the central concept in the architectural discourse that so far has proven to withstand theoretical framing (McLuhan 1964). The basis for this theoretical assumption is that space is not a void left by solid matter but instead an emergent quality of action and interaction between individuals and groups with a physical environment (Hillier 1996). In this way it can be described as a parallel distributed system, a self-organising entity. Extrapolating from Luhmann’s theory of social systems (Luhmann 1984), a spatial system is autonomous from its progenitors, people, but remains intangible to a human observer due to its abstract nature and therefore has to be analysed by computed entities, synthetic cognisers, with the capacity to perceive. This poster shows an attempt to use another complex system, a distributed connected algorithm based on Kohonen’s self-organising feature maps – SOM (Kohonen 1997), as a “perceptual aid” for creating geometric mappings of these spatial systems that will shed light on our understanding of space by not representing space through our usual mechanics but by constructing artificial spatial cognisers with abilities to make spatial representations of their own. This allows us to be shown novel representations that can help us to see new differences and similarities in spatial configurations.

title Integrating Design and Construction with Wearable Computers
source International Journal of Architectural Computing vol. 2 - no. 2
summary Wearable computers can help bridge the gap betweendesign and construction. They can integrate thesetraditionally separate cultures by improving the flowof information between them. Using a wearablecomputer, design and construction personnel can nowexchange design information quickly and continuouslybetween the point of work on the construction siteand the remote design office. The improved iterationbetween design and construction and much strongerconnection between design personnel andconstruction site afforded by wearable computers maypoint the way to a new kind of integratedarchitectural process. In this study, the goal was todetermine the value of wearable computers inintegrating design and construction by measuringspecific performance characteristics.The resultsinclude findings on productivity, rework andcommunication quality. They reveal that wearablecomputers can improve communication quality andreduce rework, but may have an initially negativeimpact on productivity. These findings suggest thatwearable computers may play a key role in futurebuilding projects, helping to bridge the current dividebetween design and construction.

summary Electronic sensors, controllers, displays and actuators can significantly enhance the value of physical models as processes of use, interaction and transformation take center stage in various fields of design. These technologies allow the development of novel computer interfaces for new kinds of interaction with virtual models, and in the future they will allow new types of active building components and materials for automated construction and dynamic runtime adaptations of inhabitable environments. However, embedding programmed logic into physical objects seems to confront designers and model makers with a steep learning curve outside the domains of their traditional expertise. The variety of alternative technologies and development tools in this area has a particularly disorienting effect on novices. Some early experiences however suggest that mastery of this learning curve is easily within reach, given some basic introduction, guidance and support. It is the purpose of this paper to provide designers with a starting point for explorations into this area, to give orientation and to demonstrate some possible development approaches and results.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

summary This is a paper about the introduction of architectural design evaluation application and pre-experience system of walkthrough situation in urban and street design. For this purpose, we developed a new multi-projection display system, D-vision, which has hybrid screens. D-vision is a kind of new virtual environment system that has high immersion and high resolution display performance with multi-modal interfaces. In our system, the user can experience the high sense of presence through the self-walking behavior to move and force feedback manipulation of objects with the high-resolution image created from the tiled-projection system that is composed of twentyfour projectors.

title Communication and Value in Networked Design Coalitions

summary The advent of the Internet has led us to believe that we live in an era of unprecedented globalization. In the field of building design, we now expect both that the local market for design services will be altered, and that many firms will take up the opportunity to pursue commissions beyond their local market. To some extent this is true, but it is instructive to recall that in the 19th century London based architectural firms and public works designers designed buildings throughout the Empire. Designing for projects beyond the local market is not new, what is new is our expectation that such a task is now fundamentally altered, made easier and more transparent, by the abundance of new communications technologies.It remains the case that working outside one’s local context is difficult and that when doing so, problems are likely to arise out of cultural differences. Distance too imposes its burdens, as the possibility to meet other members of the team face to face is reduced as the travel costs increase. This breaks down the possibilities of building informal networks among the individual designers working for the firms that are members of the design team. A re-instantiation of this informal network can only be done on the basis of a model of formal and informal communication in the design team. Many of the difficulties of collaborative work outside one’s local market are problems that have already been with us a long time. These problems arise out of the fact that buildings are designed by heterogeneous groups of people. The members of such groups must communicate with each other to share information and coordinate decisions and actions. Yet they are in different relations to the project at hand and have differing values arising out of their different backgrounds. This leads inevitably to conflict. Therefore, if we are to discuss communication and value then we must devote our attentions to conflict.

title Rapid Prototyping Techniques for Building Program Study
source CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 655-670
doi https://doi.org/10.52842/conf.caadria.2004.655
summary This paper is original research that demonstrates new design possibilities for evaluation in the schematic phase of design through the use rapid prototyping as a tool of representation verses 2D drawing. These program shapes are created from CAD files using a threedimensional printing and laser cutting CAM tools. This way of working is in response to two dimensional plan representation and evaluation (Mitchell 1976). This research combines the best of the visual aspects of plan representation and the formal representation of solid block modeling. The models in this paper demonstrate the building’s physical scale of spaces, building use and overall form. Resulting models will demonstrate a new way of designing in CAD one that combined physical and visual ways or representation.

title A Web-Based Approach to Transferring Architectural Information to the Construction Site Based on the Bim Object Concept
source CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 613-622
doi https://doi.org/10.52842/conf.caadria.2004.613
summary The current means of transferring architectural data to the construction site depends mainly on the drawing either manually or electronically drafted both in physical or digital formats. The printed or manually drafted drawing is being replaced with the digital version that can be accessed with a PDA. There are many benefits of the digital form over the physical form. However the full potential of this medium has not yet been fully exploited. The new CAD paradigm, BIM (Building Information Modeling), suggests that all the building information can be represented as a digital database that constitutes the information about the building elements as three-dimensional geometry, as well as, properties and specifications in the form of objects. This paper describes the process to convey the information about the CAD objects to the construction site through the web by extracting the properties of the objects into an XML file which can be queried for the needed data.
